Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and disrupting cell wall cross-linking, leading to cell lysis and death.

0.5-1.2 hours in normal renal function; prolonged to 5-30 hours in severe renal impairment (CrCl <10 mL/min)
Clinical Note
moderateCephalexin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Cephalexin."
Clinical Note
moderateCephalexin + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Cephalexin."
Clinical Note
moderateCephalexin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cephalexin."
Clinical Note
moderateCephalexin + Sulfisoxazole
1.5-2 hours (prolonged to 20-30 hours in severe renal impairment; dosing adjustment required for CrCl <50 mL/min).
